a. No contract or agreement executed pursuant to this charter or other law shall be implemented until (1) a copy has been filed with the comptroller and (2) either the comptroller has registered it or thirty days have elapsed from the date of filing, whichever is sooner, unless an objection has been filed pursuant to subdivision c of this section, or the comptroller has grounds for not registering the contract under subdivision b of this section.
b. Subject to the provisions of subdivision c of this section, the comptroller shall register a contract within thirty days unless the comptroller has information indicating that:
i. there remains no unexpended and unapplied balance of the appropriation or fund applicable thereto, sufficient to pay the estimated expense of executing such contract, as certified by the officer making the same;
ii. that a certification required by section three hundred twenty-seven of this chapter has not been made; or
iii. the proposed vendor has been debarred by the city in accordance with the provisions of section three hundred thirty-five.
c. The comptroller may, within thirty days of the date of filing of the contract with the comptroller's office, object in writing to the registration of the contract, if in the comptroller's judgment there is sufficient reason to believe that there is possible corruption in the letting of the contract or that the proposed contractor is involved in corrupt activity. Such objection shall be delivered within such thirty day period to the mayor setting forth in detail the grounds for the comptroller's determination. After the mayor has responded to the comptroller's objections in writing, indicating (i) the corrective actions if any, that have been taken or will be taken in response to the comptroller's objections, or (ii) the reasons why the mayor disagrees with the comptroller's objections, the mayor may require registration of the contract despite the comptroller's objections. Such response by the mayor shall not serve as the basis for further objection by the comptroller, and the comptroller shall register the contract within ten days of receipt of the mayor's response.
d. The requirements of this section shall not apply to
(1) an emergency contract awarded pursuant to section three hundred fifteen or to an accelerated procurement as defined under section three hundred twenty-six, provided that the agency shall, as soon as is practicable, submit any such contract to the comptroller for an audit of the procedures and basis for the determination of the need for an emergency or accelerated procurement, or
(2) a contract awarded pursuant to this chapter for the provision of goods, services or construction that is not to be paid for out of the city treasury or out of moneys under the control of the city, provided that the board of the entity awarding such a contract shall within ten days of awarding contract, file a copy of such contract and any related materials specified by the mayor, with the mayor or the mayor's designee for purposes of section three hundred thirty-four of this charter.
